MARKET-QUOTATION INDICATOR.

'appertains to make and use the same.

Our invention has for its object to provide an improwed apparatus for indicating changes in market prices, quotation scores, combinations of figures, etc., and the particular object .had in view is the provision of a highly eflicient electrically controlled quotation indicator for use in grain and stock exchanges.

To the above ends the invention consists of the-novel devices and combinations of de ices hereinafter described and defined in the claims.

In the accompanying drawings, wherein like characters indicate likeparts throughout the several views, we have illustrated a form of the improved indicator whichhas been put into actual use and-found efiicient for the purposes had in View.

electrical connections of the entire apparatus.

In the present illustration, the indicator is made to show grain quotations in digits and fractions, and also the four grain delivery months. 'The figures and letters, shown by solid lines in Fig. l, are indications, while those indicated by dotted lines are possible indications.

The case or framework 1 of the indicator proper may be made of wood or any other suitable material arranged with suitable light-proof compartments. The dial or face plate of the casing 1 may be constructed in different ways, but should have transparent or translucent characters over the several light compartments. Preferably, however, the said face is built up as follows: First, a color screen metal or other opaque material 2- from which is cut the stencil of the desired indication, then a sheet of tracing cloth or vel lum 2, and finally, a plate of ground glass 2, all of which parts are firmly pressed together and are thoroughly stopped at their edges to prevent light rays from showing anywhere but through the stencil.

The glass on each side of the stencil is for the purpose of holding the stencil firmly in line and producing a clear, sharp cut indication. The tracing cloth and ground glass make an evenly illuminated indication, regardless of the position of the lamp; and, furthermore, screens the stencil from view when not illuminated. The color screen is used for the purpose of projecting the indication in some color, such as red or green,

contrasting with'the ground glass front and producing an indication which can be easily read in a well lighted room.

In Fig. 3, which shows the arrangement of the component parts of the face plate, the plate 2 is at the inner side, and the plate 2 at the outer side of the indicator frame or box to which the said composite face is suitablysecured at its margin.

. The case 1 of the indicator is formed with a circumferentially spaced series of light compartments 3, in which are contained electrio lamps 4. The stencil in the dial is formed with fraction indications that cover the light compartments 3, as shown in Fig. 1. Within the circular zone which includes the fractional light compartments 3, the case 1 is formed with a wheel compartment 5 and four light compartments 6, in each of which latter is a small electric lamp 7. The stencll of the dial, immediately over the compartment 5,-is cut away, and over the compart ment 6 is cut away to indicate the. four grain tgeliyery months, i. 0., May, July, Sept. and k ec.

The numeral wheel 9, shown in detail in Fig. 4, carries ten numeral stencils, each 111'- dicatingone of the digits 0 to 9 inclusive,

' any one of which figures are adapted to be turned directly in front of the opening cut in the stencil of the dial. This numeral wheel is carried by a shaft 10 mounted in 'a bracket 11 and other suitable bearings (not shown) on the case 1, and provided with two ratchet wheels 12, and 12 arranged to drive the wheel in opposite directions. To correspond to the numeral wheel carrying the ten digit indicating stencils, the ratchet wheels 12 and 12 are each provided with ten teeth. Also as preferably constructed,

the wheel 9 is provided with ten spokes,

and to lock this wheel in proper pos1-.

tion so as to have one or the'other of the diglts of the stencil register with the open- ,mg in the dial, a solenoid 13 and a movable spring-pressed core 14, the latter having a bevel head 15 with lock notch 15, is provided. Normally, one of the spokes of the numeral wheel is'engaged in the notch 15 of the head 15, the solenoid 13 being normally ,deenergized. The lock made up of the head 15 is released from the spoke when the solenoid 13 is energized through connections presently to be described.

For indirectly imparting motion to the ratchet wheels 12 and 12*, respectively, are magnets 16 and 16. Armatures 17 and 17, respectively, cooperate with the magnets 16 and 16*, and these armatures are secured, -respectively, to the ends of sliding bars 18 and 18", which in turn are provided, respectively, with spring-pressed driving dogs 19 and 19 that engage the respective ratchet wheels 12 and 12*. Normally, or when the magnets 16 eight switches 22 may be of any suitable shall assume that they are normally open. These switches 22 are connected on one side by wires 23 to lamps 4 of the so-called' fractional light compartments, in front of which the stencil of the indicator dial is rovided with corresponding fractional in ications.

to a wire 24 shown in the form of a circle 111 the diagram view Fig. 10, and this wire nected by Wire 25 to one of a pair of lighting mains 26. The other lighting main 26 is shown as connected, by wire 27 to a lamp 28 that is located'and is suitably supported. inside of the rotary numeral {wheel 9 (see Figs. 2 and 10). The wire 27 is shown as provided with branches 27 ,with which any oneoof the eight wires 23 may be con nected by closing of one or the other of the switches 22. A normally closed switch 29 which, as shown, is located at the switch board SB, is interposed in 'the wire 27. Also on the switch boardis another group of four normally open switches 30 that are connected on one side, bywires 31, one to each of the lamps 7 that are located'within the light compartments 6. The four Wires 31 are connected, by a wire 32, to one of the lighting mains 26, this connection, as shown, being made through'the wire 25. The wire 32 is connected, by a wire 32, 'to

tended at 27 and is connected to a fixed contact 34 (see Fig. 10), which two contacts 33 and 34 are-spaced apart but in close proximity and are normally on aged by a metal bridge bar 36 of a movab e armature made up of the said bar 36and of another bar 37, which two bars are insulated from each other.

ed to be moved by relay magnets 38, and when moved, its bar 37 is-adapted to be en- 36 will be disengaged from the contacts 33 and 34. The contact 39-is connected, by a wire40, to one terminal of a battery 41, the other terminal of which battery is connected by a wire 42 to the yielding contact 21. f The other yielding contact 21* is connected, by a wire 43, to the armature bar 37, and the in this wire 43. A wire 44 connects the two Fig. 10. The wire 27 at the switch board SB is provided with branches 27 through four switches 30. The eight switches 22 constitute one group, and the four switches l and these groups are prefera 1y arranged in type, but for the purposes of illustration we 24, as shown in said diagram view, is con a fixed contact 33, and the wire 27 is ex- The-armature 36--37 is adapt-.

All of the, lamps 4 are connected on one side gaged with a fixed contact 39-, while the bar solenoid 13 already described is'interposed armatures 17 and 17, all as best shown in y which the circuit, including the wire 27, I may be closed by movemenbof one of the 30 constitute another grou of -switches;

esaoas arrangement wherein the closing 0t any one of the switches ot a groupv opens or insures opening ot' all of the other switches of that group;

For controlligigg the position or the nu.- meral wheel 9 om a distant point, to-wit, from the switch boardwhich is located at a point more or less remote from the indicator, we provide an. electrical controller, which includes a pulsator or means for sending electrical impulses. over the controlling line, so. as to thereby intermittently energize the magnets 1.6 and 16?, which magnets, as wall as the coiperating ratchet devices, constitute part of this controller and, as already described, are located at the indicatorproper. The said magnets 16 and 16f are connected, respectively, by wires 45 and 45 to! fixed contacts 16 and 4:6 located on the switch board and, as shown, being in the form of spring blades secured to but insulatedfrom a lug 47. oli a bearing plate 48, which latter is rigidl secured to the bottom oi the said switc board, as best shown in 8 and 9.

now the arts that make up what, may be designate as a. pulsator, the numeral 19- indicates a stud that projects from the bearing plate 48 just below the contacts 46 and on which isv mounted an oscillatory sleeve 50-. This sleeve 50 has a segmental contact flange 5 1, which, in its normal position shown in Fig. 9, engages with neither of the contacts 46416#, but which, by slight oscillation of said sleeve, may be engaged with either thereof, according to the direction of oscillation. This sleeve 50,. andhence, the segmental contact 51, is connected by a wire 52 to: the relay magnets 38 and thence,'as shown, by wires 53 -54: to the two escape-ment magnets 16 161 of the electrical controller. rangement described, the wire 52 constitutes a. common. return from thel magnets 1616* and 38, and interposed therein isa battery or other source of electrical energy 55. Also as shown, a normally closed switch 56 is interposed in the return Wire 52.

Jiournaled in. the hub of the bearing plate.

4G8 and in a. bar 57 secured thereto, is a con.- troller shaft 58 which, atone end, is provided with a star wheel or notched disk 59 having ten notches, preiicrably of approximately semi-circular form. The notch of this disk, which is at the bottom thereof, engages a small wheel 60 shown as ournaledto the ends of a pair-of arms. 61 carried by the sleeve 51% of the segmental contact 51. A coiled tension spring 62, connected to one of the arms 6.].- and to the bar 57'. normally holds the parts 61, 50- and. 51 in their inter mediate positions shown in Figs. 8 and 9; The shaft 58 also carries a. second star-wheel 63., that is engaged by a roller or wheel 64 In the arcarried at the free end. of a downwardly spring-pressed retaining pawl 65, which latter is pivoted to. a suitable support on the bearing plate 48 and serves to yieldingly hold the shaft 58 and main. star wheel 59- in any one of the ten positions in which it may be set. At its other end, to-wit, its left hand end as shown in Fig. 8-, the shaft 58 is provided with an operating arm 66 that is preferably pointed and coiiperates with an annular scale or indicator ring 67 secured to the adjacent face of the switch board SB,

as best shown in Figs. 7 and 8. This operating arm 66 is shown as provided with a finger-piece 68 by means of which the said armature 66 and hence the shalit 58 and parts carried thereby may be rotated or given, arotary step by step movement.

By means of the electrical controller above described, the numeral wheel 9-n1ay be given any desired number of steps of movement in either direction, and hence be set with any one of its digi s exposed at the (LliLh. If, for instance, it is desired to move the numeral wheel so that its digit 2 will be exposed atthe dial, the operating lever 66 is moved the direction of the arrow marked on Fig. 7 until its. pointer registers with the numeral 2 on the ring 67. This movement ot thea-rm 66 will, of course, impart corresponding movement to the shaft 58 and tothe star wheel 59, thus. imparting two steps or notches of movement to the latter in the direction. of the arrow marked on Fig. 9. 'Each notch or step of movement imparted; to. the star wheel 59 will, acting on the wheel 66",. cause the sleeve 50 and segmental contact 51 to make two. oscillations, and.- each such oscillation will engage the said segmental contact 51 with the spring contact 46 and again separate the same. Thus it will be seen that for each notch" or step of movement imparted to the star wheel 59, an electrical impulse will be sent over one side or the other of the controller circuit. For instance, .in the. illustration just above given. two electrical impulses will be sent over the circuit including wire 45, magnet 16, wires 5453, relay magnets 38 and return wire 52. This causes magnet 16 to twice reciprocate bar 18, thereby causing the pal-W1 19 of the latter operating twice on the ratchet wheel 12 to impart two steps of movement to the numeral wheel 9,. as already stated. The numeral wheel may be returned to. normal or zero position by continuin-g the movement of the arm 66 and cam or star wheel 59 in the same direction noted, to wit', in the direction of the arrow marked on F 7, while it may be restored to. normal position a backward movement oi the said arm- 66.31.1161 cam wheel 59 lVhcn the said cam wheel 59" is turned back Ward, the segmental contact 51 will be iiitermittently engaged with the spring,v contact 46*, and the clrcuit which is then intermittently closed will be through wire 45*, magnet 16*, wires 54 -53, relay magnets 38 and return wire 52. This intermittently energizes the said magnets 16 with the result th3,l'1 'tl16 bar 18 will be oscillated and its pawl 19, operating on the ratchet wheel 12, will impart the required backwardmovemer'it to the said numeral wheel.

It is thus evident that the numeral wheel will follow movements of the controlling arm 66 in either direction.

Whenever the controlling circuit above de-' scribed is closed. either through the magnet 16 or through the magnet 16%, it has been noted, the relay magnets 38 are energized. The first effect of thisis to move the relay armature so as to remove the armature bar 20 36 from the contacts 33-34, thereby breaking the circuit through the lamp 28 which is within the numeral wheel. This puts out the light'in the numeral wheel so that subsequent movement of the said wheel is .not

I made visible on the dial. This same move-,

ment of, the armature causes the bar 37 to enga e fixed contact 39 and thereby closethe local circuit through wire'40, battery \41,

- contact 21 wire 44, contact 21, wire 43 and 30 solenoid 13,fthe'reby ener izing the solenoid and causingt'lae latter to raw downwardthe lock '15 and thereby release the numeral wheel so that it will be free for movement under the action of whichever of thetwo magnets 16-46 is energized. The, yielding or follow-up contacts 2 1.an d 21 will maintain engagement with the cooperating armature 17 and 17*" long enough to permit initial movement of the numeral wheel, but will 40 break the circuit through the solenoid 13 1 and thereby release the lock' 15 at a time early en'ough to permit the said lock to be again ready to lock the wheel when it has completed its step-of. movement. Asis evident, whenever e cam wheel 59 completes its step of movement, the spring 62 see Figs.-8 and 9) will throwthe segmental con tact 51 back to normal positlon, thereby breaking the circuit through whichever of .50 the magnets 1616'happens to have been energized, and also breaking the circuit through the relay magnets 38. This, of course, permits the armature 36 to be restored to its normal position, shown in Fig.

55 10,'under the action of a suitable spring. (not shownfithereby again closing the cir-- cuit through the lamp 28 which 1s.within the-numeral wheel, and causing the illumination of the digit of the wheel located in front of the dial. -Also.when the magnet 16..-,16 are deenergized, the cooperating bar 18or 18* will be restored-to normal position by its spring 20 or 20 as the case may be.

.- .By closing the proper switch 22 the circuit may be closed throu h the lamp 4, which will cause the proper ractional indication on the dial of'the indicator; and by closing the proper switch 30, the circuit -may be closed through the lamp 7 which will give the proper delivery month indication on the dial of the said indicator.
